My wife and I stayed here for 5 nights in total and feel it suited our needs just fine. Here's a quick list of pros and cons from our standpoint so you decide for yourself if its somewhere you want to stay.

Pros:
- Nice big rooms, the second one we stayed in had AC (nice in the hot summer)
- Location was good. Its at the southern end of San Telmo (older cobblestone area of the city) and a quick walk to the restaurant area of that neighborhood. It is bordering on the La Boca neighborhood with a big park separating it, which we were told we should not walk into (the neighborhood, not the park) if we could help it, but we never felt unsafe day or night.
- Day staff was excellent. Sol, the woman who helped us, had excellent english and went way out of her way to help us book bus and hotels for the second part of our trip. Thanks Sol!
- Price - for the price in Buenos Aires we thought it was great value. We saved money by not booking online ($65 per night as opposed to $85 at the time).

Cons:
- Free WIFI didnt work on the second floor and up (just small inconvenience)
- Free breakfast left something for Americans or Europeans to be desired. Breakfast in general in Argentina is not great to begin with, so its not necessarily the hotel's fault.
- Night staff wasnt as proficient in English at the time, but still very friendly and we figured it all out

Overall it worked out and we were thankful for all the help during our stay. If we return we would also now considering staying up in the Palermo Viejo area (if we could afford it). It was also a very cool, hip neighborhood up north that seemed to have a lot going on.

Family-run hostel with very few rooms, which gives them the opportunity to get to know their guests and help us with anything we needed.
I wanted to surprise my boyfriend and take him to the Boca soccer stadium for a match and they got the tickets for me, transportation etc and kept the secret until the end...!!!! It definitely is a warm atmosphere and you are looking for something relaxed, quiet and homey, this is your hostel. Being all locals, they are also full of great tips to help you discover the fantastic places that Buenos Aires has to offer that dont appear in the travel guides. I will definitely come back to Noster Bayres!

This place felt like home. I stayed briefly on my way thru to Peru very jetlagged. On my return there was no need to give my name, they knew who I was. The staff were very helpful and when the English speaking staff member was on duty, even better ! Great suggestions for dinner a short walk away. I usually do the 4-5 star hotel stuff, but I must say if this is budget and I need pay $30 usd per night, (single room with ensuite) I will do it again ! Rooms were spotless, plenty of hotwater and water pressure, and most of all it was quiet ! What more could you want in a great local area where I felt like the only tourist - perfecto !

A great hotel in a very nice part of B.A. We loved the staff who went out of their way to be of help to us and it was a delight to stay in rooms that were decorated in different themes (we stayed twice on this trip, at the beginning and at the end). Frankly, this hotel should be one of the top ones in every guide book and we were delighted to find it.
I would recommend Noster Bayres to anyone who wants to spend some time in B.A. I am sure they will enyoy it as much as we did.
Thank you to all the lovely people we met while there
