We had a wonderful stay at Martha's apartment. Check in and communication were smooth and easy, and the apartment was exactly as advertised. Five of us (two adults, 3 kids) stayed very comfortably for a week. The kitchen had everything we needed to cook everyday, and there were two full grocery stores (not to mention the market) two minutes away by foot. There were, as well, several restaurants and cafes close by. The apartment had all necessary toiletries, and then some. Martha has thought of everything.
If you are considering this apartment, you should know: a) there are a lot of stairs, so it's not ideal for anyone with mobility challenges; b) it's a true 20 minute walk to the center of town. Public transportation is easy and fast. A taxi cost 7-10 euros, depending on where we started downtown. The locating was great for us, as it allowed us to get out of the noisy center every evening and relax; c) the apartment is larger than it looks, and incredibly comfortable! But the sleeping arrangements are not ideal if everyone needs 100% privacy (we didn't).
Finally, we visited in the middle of a crazy heat wave (certainly not Martha's fault!), so the apartment was hot. There were a couple of fans available, which helped some, but it's not an easy apartment to cool down.
Overall we had a great visit and we're grateful to Martha for her hospitality!
