Stayed at Duval Apartmnets several times and advise this to my friends and relatives for their Warsaw visit. The apartments are very nice, each has its own style. They are clean, comfortable, the right size and the location is perfect.
WiFi internet access, TV and DVD player, small fridge were also available.
People who work here are great, thus I highly recommend this place.

Perfect location in the old town, spacious room, huge bed, big bathroom, nice breakfast. There was a fridge and a kettle in the room but no other cooking equipment. There's however a cafe and an Italian restaurant in the same house which is convenient.
Martin, one of the hosts, was really nice and helpful. Would definately stay here again.

Duval apartments in Warsaw is great! The location is in the beautiful old town and close to many things. The apt building is beautiful and has a lot of character. I stayed in room #4 (the glass room). The room was spacious and clean. The bathroom is clean. The shower size is fair. Free WIFI worked great! The host, Martin was the nicest person. He's always gracious, from early morning to the late night.  One thing I have to mention is no elevator. So this apt may not be for people who have problems with their knees. But otherwise, this apt is GREAT!! I recommend this apt to anyone :)

We stayed here for eight nights in May, in the Polish room, and it was better than ever for this our third stay. Because of its location, It is amazing to discover the wonders that are so close, including the Barbican, just a step away. Agnieszka and Martin have both become friends as well.
