I came with my wife for a conference at Ifema. Checking was seamless, even though we arrived at night. Fernando, is always available and helpful.
The neighborhood is very quiet and clean. The apartment itself is large and stylish. It is a 4 minute walk from the Metro (really easy to get to). Using the metro was 40 min door to door from Ifema, by Uber 11 minutes. It is also located 40 min for plaza mayor via metro.
Really positive experience. When I return to Spain will again try to rent this great Loft again.
