This is a bright, spacious two bedroom apartment in Tetuán, about 10-15 mins by taxi north of the city centre. If you want to be right in the centre you will need to think about public transport / taxi times and costs but it suited us perfectly as it was in a residential area and quieter, giving a better feel for 'local Madrid life'.
The flat is well located, with a fruit shop, supermarket, cafes and bars all within five or less minutes walking time. There is a small balcony with a table and two chairs where one can sit and work, eat or have a drink. Inside the main bedroom has an ensuite toilet and shower which was great and the second bedroom also has another bathroom opposite. The kitchen has the basics and is good enough for self-catering. There is also a tv, sofas, and a dining table and chairs, although some of the furniture is well used and could do with being updated / replaced. That said it it will be good enough for most people.
The flat is managed by Minty, a letting agent who did a good job of checking us in and communicating before and during our stay. We had an issue with the patio table being broken and although it took a few days, it was replaced and they were overall very helpful and responsive - one felt they really were trying to ensure one had good stay.
Overall, if you don't mind being a little out of the centre, you can't go wrong with the flat and also given the support from the letting agent.
