We were a group of 9 and the flat was perfect. We had access to the 3 bathrooms, the rooms are very conformable with furnished towels for each bed. Coffee and tea in the morning, everything you need, no AC but some very convenient fans in each room.
Super accessible neighborhood and very efficient communication through WhatsApp ! I totally recommend this place for a large group of friends or family, but keep in mind that the building is very calm and there are strict rules on that but you know before coming :)
Hope to come back soon.
