We (myself, my husband and 2 kids aged 14 and 9) had a great stay at the apartment. Juan Carlos met us and gave us a thorough run down of how everything in the apartment worked, answered our questions about the neighbourhood and gave us a map along with some very good suggestions re. places to visit and eat.
The apartment was spotlessly clean, well equipped and comfortable and just like the photos. It's location worked very well for us. We were able to easily walk to many places, or catch the metro. We used 4 x T10 tickets between the 4 or us over 4 days, which worked out to be very good value.
The neighbourhood felt safe and friendly. There's a Lidl supermarket a few blocks away, also a Carrefour Express as well as many smaller 'corner shop' type supermarkets. There's a bakery/coffee shop right next door to the apartment, which we visited often.
We all slept very well in the apartment. Our only issue was that the neighbour's TV was very loud and could be heard from the main bedroom. We made up the comfortable sofa bed in the living room and slept well there.
