the location was very convenient.
we booked 2 double rooms, 1 room was very small (you could hardly walk between the closet and the bed), the other room we booked was better. other rooms we saw during our stay were larger so it seems to vary considerably - perhaps ask to see the rooms if possible before taking the room?
the smaller room opened into an enclosed courtyard which other bathrooms opened into so if the window was open you heard all bathroom noises...
the room was dirty - long dark hairs over the tiled floor of the room and bathroom - quite disgusting. dust-balls behind the door was further evidence of a general lack of cleanliness.
the airconditioning was turned off at approx 7.00am each morning. the first morning we thought it was a mistake so let it pass but it was still off when we returned in the evening, after negotiations they turned it back on but it was off again the next morning. the 2nd morning i found the airconditioner had leaked all over the luggage - the luggage rack was under the airconditioner.
i would not recommend this hotel.

Check-in took ages. The elderly man at the reception desk kept us waiting 15minutes while he completed some other paperwork, and then insisted on filling in multiple forms before giving us our key. Luckily, the room was OK, clean beds and bathroom, and a nice cool room with fully functioning air conditioning unit.

Good for a couple of days stay.

The Londres is around the corner from the Fine Arts museum and about a 10 minute walk from the Cathedral. The location was good and the hotel is basic but clean. The desk staff does not speak any English but that is generally not a problem. We did have trouble understanding the night clerk about a taxi we had ordered for the next day but the taxi came on time so it worked out. If you are looking for a little bit of luxury this is not the place for you but what you get is comensurate with the fairly low rate that they charge. If we returned to Sevilla I would stay in a different neighborhood but this was fine for the two nights we were there.

this hotel is located a bit outside of the normal tourist path but still very near to the main attraction. Hence the neighborhood is calm and we feel we share more of the sevillan way of life.
The hotel itself is nothing fancy. Rooms are clean but noisy, hotel staff is there to hand your keys but don't expect much more.
Id recommend this hotel to anyone who just want a place where to crash after wandering hours and hours in the street of sevilla.
