Nice, little, very clean flat that had everything we needed for 4 people. Nuria wrote us before we arrived and told us everything we needed to know beforehand. Olga welcomed us exactly as Nuria had told us. The neighborhood is fantastic, very lively and filled with small shops, bars and restaurants. The flat is in the back, so it's still very quiet. You can walk to all the main attractions or take the metro (5-10 minutes walk max.) a few stops. A really nice weekend in Madrid with delicious (and cheap) food and wine!
