Miguel's place is wonderful for a larger group of 5-6. We had 6 total and there was ample room. The location is perfect, just across the street from the Plaza de Toros, a couple blocks to the Cathedral/ la Giralda, very close to busses, to lots of good restaurants, walking distance to Triana and Plaza de España....couldn't have asked for much better location! The amenities are also very nice, great rooms and bathrooms/showers. Kitchen was great for making some simple meals and had all we needed.
Check in/out is super easy using an app and a key box, everything was clean and comfortable, lots of towels, and he even left some snacks/drinks for us. Lots of reccomendations for things to do are left on the little shelf under the kitchen table, we found some good things that way!!
2 very little things to note--the water heater is small so laundry and showers use the hot water very fast (just something to keep in mind if you have a larger group). Also, we woke up at 5am one morning to make a day trip to Tangier, Morocco and the downstairs neighbor said we were walking too loudly too early--although we were walking quite normally, the walls/floors are on the thinner side so even normal noises can travel through the building.
